That is it in simplest form, there is nothing else you can do to it.
Hope this helps :)
Answer:
Step-by-step explanation:
I think the one you want is the last one, but I've never called it that.
21x^2 + 147x + x^3 + 343
x^3 + 343 is a cubic binomial. It factors into (x + 7) (x^2 - 7x + 49)
21x(x + 7) + (x + 7)(x^2 - 7x + 49)
(x + 7) [ 21x - 7x + x^2 + 49)
(x + 7) [x^2 + 14x + 49]
(x + 7) ( x+7)^2
(x + 7)^3
It's the only answer that does factor. There must be a simpler way of doing it, but this will give you the right answer.

Answer:
C
Step-by-step explanation:
The maximum/minimum values is simply the y-value of the vertex. Since both of the functions have a negative leading coefficient, they will both have maximum values.
For Function 1, we can see that the vertex is at (4,1). Thus, it's maximum value is at y=1.
For Function 2, we need to work out the vertex. To do this we can use:

To find the vertex.
Function 2 is defined by:

Therefore:


Thus, the vertex of Function 2 is at (2,5). Therefore, the maximum value of Function 2 is y=5.
5 is greater than 1, so the maximum value of Function 2 is greater.
The answer is choice C.
